It might be changing from firmware version to firmware version since the start of Amazon shipping complete images.
(About the time those directions where written.)
I don't think anyone ever checked if or when they change the storage layout.
Geekmaster wrote a tool to locate the start of the kernel and the start of the partitioned area.

That information is contained in its environment settings (as a byte offset, not a block offset).
You can display that information while in u-boot with the "printenv" command.
